| Abstract/Contents: | "In field plots of tall fescue (Festuca arundinacea) 'Fawn', planted at three densities, severity of brown patch disease, caused by Rhizoctonia solani AG 1-IA, increased with increasing plant density. Canopy temperature, leaf wetness duration, relative humidity, and canopy air temperature were measured during the experiment using microenvironmental instrumentation. No differences were found for any of the environmental parameters among the three plant densities that could explain observed differences in disease. In a growth chamber experiment, 'Fawn' planted at three densities was provided with uniform environmental conditions. R. solani mycelial growth and spread of necrosis through these canopies was observed. Hyphal growth between grass blades occurred more readily in high seedling densities, and differences in bridging ability was related to rate of necrosis development. We conclude that the affect of plant density on disease in the field was not due to canopy microclimatic influences, but was related to proximity of grass blades within the canopies." |
